I bought large rifle primers for my.243 prior to receiving the gun with the thinking that those were what was needed only to find out that the rem 9 1/2m is called for. What if anything would I be losing using the large rifle primers. I do have some fed 215's and some Winchester mag primers but was hoping to hang onto them due to the shortage of primers. I bought 2,000 of the large rifle with nothing else to use them in. Thank you
 
I don't consider the 9 1/2M a magnum primer, not even close to a Cci 250 which is not as strong as a 215 much less a Win Mag primer. So, you should be very well with the 9 1/2M in the 243. If you try R#26 in the 243 with 100g, the 215's is what I would try first.
